FYI:I put it on mine last night (you'll need to use the latest version of the DSDownloader, on their site) and had no problems with my DTP tune, everything worked fine. Per this post http://www.modularfords.com/forums/773469-post6.html colediablosport says "Usually we do post what the rev updates include. But on this particular update is adds OEM select options under OPTIONS menu. It will allow a user to select between Steeda,C&L,Procharger,VTech,SLP,JLT tunes. You have to select which tunes to install. But this is all that is included in the r35 update."

I do see all of the options listed above, as well as a traction control option. I left the TC option unchanged though.
